Unifi USG fan bracket

This is a fan bracket for a Unifi USG router. The USG runs hot and I wanted to add a cooling fan. You can remove the existing bracket install this with the existing screws and press / friction fit a 40mm Noctura fan. I printed this at .2mm and draft. The screw holes are not the greatest. I was too lazy to correct this. It's good enough to work. Don't tighten the 4 screws too tight or you may separate the layers on the print.
